The radiocarbon ages indicated here are not directly equivalent to calender years. Lab No. The laboratory is a unique identifier given to each radiocarbon sample. The prefix identifies the laboratory that processed the sample.
The 'Wk' prefix shown here indicates that these samples were processed at the University of Waikato Radiocarbon Dating Laboratory. Site The site identifies the specific archaeological site the sample came from.
Site s in the United States are based on the "Smithsonian Trinomial System" where each State has its own e. However, not all countries have their own specific ing system. Material It is important to know what kind of material was dated, as materials are processed and calibrated differently.
To learn more, follow the links at the bottom of the. Context It is also useful to know which part of a site that samples came from e. Conventional Age Most laboratories report radiocarbon determinations as "Conventional Ages. Conventional ages cannot be directly translated into calendar years; this requires a further step. Calibrated Age Ranges When radiocarbon dating was developed, it was assumed that the concentration of 14C in the atmosphere was constant over time. However, we now know that it has varied over time, mostly because of changes in the earth's magnetic field.
In order to compensate for these fluctuations, conventional radiocarbon ages need to be adjusted using a calibration curve.
Fortunately, there are a of computer programs that can perform this task. In addition, we also know that marine samples are susceptible to fluctuations in carbon 14 because of ocean upwelling and other factors. New Zealand Lab No.Carbon dating data table
